Patented ay 3, 1932 sra'ras PATENT i PAUL M. HOENSHEL, OF PORT MYACA, FLORIDA, ASSIGNOR TO MAYACA COMPANY, 0F MIAMI, FLORIDA, A CORPORATION OF FLORIDA COMBINED IRRIGATION DRAIN AGE PUMP Application led. July 21,

This invention relates to a combined irrigation and drainage pump.

An object of my invention is the construction of a very elicient and relatively inex- '5' pensive pump for use in irrigating land or, if desired, for draining land.

Another object of my invention is the construction' of the body of the pump-casing which is provided with efficient and novel 1o means whereby one side or part of the casing may be removed for allowing water to more freely enter the casing.

A still Afurther object of my invention is the construction of a novel rod-screen at the l bottom of the pump casing for increasing the eiliciency of my ump.

A still further o ject of my invention is the novel arrangement of the bracing beams and the novel construction of the thrust bear.

ing, etc.

This application discloses valuable improvements over my prior United States Patent No. 1,737,372, combined irrigation and drainage pump.

With the foregoing and other objects in View, my invention comprises certain novel constructions, combinations and arrangements of parts as will be hereinafter fully described, illustrated in the accompan ing drawings, and more particularly pointe out in the ap ended claims.

Referringto the drawings by numerals, 1 designates the vertical uprights that are driven into the bottom of the canal; these uprights 1- are creosoted or otherwise treated prior to positioning for increasing their durability and life. Sets of timbers or beams 2 connect the uprights 1 near their upper ends. These beams, 3, in each pair, are notched (Fig. 2) vvto lit upon a corner of an vupright 1, and bolts 4 extend through the uprights and the beams 3, securing them together. Therefore, it will be noted that the beams in each pair are spaced apart to allow the vertical propeller shaft 5 to extend therebetween. A bearing box or plate 6 is placed against the beams in each pair 2 and a slight horizontal adjustment of the plate 6, on its supporting beams, is obtainable, for accurate centering of the propeller shaft 5 in my pump, prior to the placing of fastening bolts 'through plate 6 and its supporting beams 3. I usually employ two bearing devices, of which plate 6 is a part, in my pump, each one resting against a set of said horizontal spaced beams l Each bearing device comprises said plate 6 with an upstanding ange 8, within which ange is a felt washer 9, Fig. 8. A suitable lubricating device 10 ,is employed for p'errmitting a lubricant to pass into the device. A slottedsleeve 11, wedge-shape in cross sec-` tion is placed around shaft 5 and a Timken roller bearing 12 is placed against sleeve 11 and Within the upstanding flange 8. thrust bearing collar 13 is secured on shaft 5 againstslotted sleeve 11. Various type propellers 14 (Fig. 1) can beused, the'eizact pitch of the same dependent upon head to e pumper against and speed of pump. A forged steel propeller of six-blade type, brazed into iron huband keyed on steelpropellershaft 5, suits most conditions, and is shown in Figure 1. I preferably use two bearing devices to take all thrust and radial load, the bottom bearing being merely a guide bearing to prevent whipping of sha as herebefore indicated, these bearing devices are mounted on the two sets of diagonal timbers or beams, crossing at right angles andv preferably two feet from each other, with pulley'15 mounted on shaft fbetween said two bearings'. The slotted sleeve 11 acts as a wedge to lock the bearing to the shaft. The thrust collar 13 is securely held on vshaft 5 by set screw 16 to prevent any-movement of said tapered sleeve 11. When my pump is Ito be used reversed, one of vthe bearlng devices is" set upside down, as indicated by dotted lines 17, to take the thrust when reversing. When the pump is only used as a lift pump, both bearing devices are set on top of the spaced beams 3 to take downwardthrust only. p

I form a horizontal Hoor 18 on the vertical uprights 2 and build-an expansion casing 19 around and above said floor. This casing is preferably constructed of boards, although it may be formed of any other suit- -able material and one sideof the expansion casing is peculiarly constructed for allowing the removal of the same for free passage of the water into the expansion chamber .formed by said expansion casing 19. This removable side is constructed by placing two vertical cleats 20 against the registering face of' two uprights 1 forming-part of .one side Yof the pump, as clearly shown in Figures 3 and 4. These cleats form registering; vertical grooves 21 on two of the uprights 1. In these grooves 21'extend the bevelled ends 22 (Eigs.

4 and 11) of the needles or boards 23. 1

use the term boards in a broad sense, meaning any suitable unit of the specific-like charL` acter. The bevelled ends 22 of each board 23 are formed in' parallelism to prevent jamming or wedging while placin the board in position or readily removing t e same -when it is desired to have one side of the expansion casing 19 open. Hook grips 25 are attached to the outer face of and near the ends of each board 23 for allowing the operator to more readily manipulate the boards. fn

In the floor 18' of expansion casing-19, I

' preferably bore vertical aperturesfor holes 26, and through these holes 26 I place screen rods 27; these rods 27 are forced a suitable distance into the bottom of the canal (Fig. f

1) thereby forming an eflicient screen around the propeller tube or casing 28. Casing 28 has an angular flange' 29 welded 'thereon at its upper edge; this ange is not only angular in cross-sectionhbut it is annular for surrounding the casing 28. The flange 29 is provided with large vertical holes 30, in'

which are fitted bolts 31 having Shanks of considerable less diameter than thev diameter of said holes, sothat the propeller casing 28 can have a certain amount of body adjustment upon floor 18 to accommodate the casing to a nicety with reference to lpropeller 14 and vshaft 5; this slight adjustment is indicated by the relative size ofthe hole 30 and bolt 31 of Figure 13. In the open bottom of casing 28 are secured horizontal vanes 32, to which is secured vertical sleeve 33- (Figs. 1 )and 6). In sleeve 33 is s'uitably mounted shell 34. Shaft 5` extends into shell 34.

Discharge culverts 35 have their inner ends opening into-expansion casing 19 any suitable distance above the floor 18. Further, any desirablenumber of said culverts 35 may be used. It will, therefore, be understood that I have provided a pump of the class described with a peculiarly constructed removableside; also with a peculiarly constructed screen formed around or enclosing the end of the propeller casing for keeping out foreign substances and thereby increasing the etliciency of the pump, and I also have provided peculiarly constructed supporting beam units for allowing the'propeller shaft to be accurately centered by means of bearing devices carried on said units.

This pumpis a radical improvement over my' original pum shown in Patent No. 1,737,372, issuedl Aov. 26, 1929, though still utilizing the reversible feature and taking the discharge from the bottom of the piunp. My puinp is now being made in various sizes from ten inches to twenty-four inches in diameter, but the accompanyin drawings have ,been made from the twenty-inch size, which suits most conditions.

The removable side, constituted by said boards 23 is generally formed on the down.- stream side, so as to permit ready lremoval when it is desired to drain water from the fields vback into the canal through the pump. By these means, the same installation handles water both on and off the land. In reversing, the boards 23 are put in place and the pump direction reversed by reversin the twist in the quarter-turn guide belt 36 Fig.

rwater in the fields rflowing by gravity through culverts into the pump, where it is thrust down through the pump. Gates (not` shown) on the inside of the field or in the pump bare then put in place to prevent water rom running back when the pump -is sto ped.

ll parts of my pump are easily accessible, and .the entire pump can be removed and replaced in a short time, under the most adverse conditions. The expansion chamber in casing 19 eliminates cavitation and exces- 69 ing an angular iange weldedf'upon its up- .culverts, avoiding the expense of concrete work in easily eroded soils. Water rises in the expansion chamber only enough to overcome difference in head and pipe friction,

and by using large diameter culverts, this is reduced to a minimum. e

My pump can be reversed by reversin the direction of rotation of the propeller gimpeller); the discharge is at the bottom of pump, and water is never raised higher than necessary; it is designed to handle water directly from the pump into culverts, avoiding 1 all open iumes, etc. the same installation acts as drainage and irrigation means, and is readily adaptable to special conditions, and

is simple in design, making it absolutely dependable, and easily installed and operated y common labor.

While I have described the preferred embodiment of my invention and illustrated the same in the accompanyingdrawings, certain minor changes or alterations may appear to one skilled in the art to which this invention relates during the extensive manufacture of the same, and I, therefore, reserve the right to make such changesor alterations as shall fairly fall withinthe scope of the appended claims. f
